Enhanced rock weathering involves adding minute rock grains to cropland soils which dissolve chemically taking up carbon dioxide and releasing plant essential nutrients. Unlike other carbon removal strategies enhanced rock weathering doesn’t compete for land used to grow food or increase the demand for freshwater. Other potential benefits include reducing the use of agricultural fertilizers and pesticides, lowering the cost of food production and increasing farm profitability.
With an ever-growing human population and its inherent demand for water, there is a critical need to monitor water resources. New technology could make it more feasible than ever to measure changes in the water flow of rivers.
How might climate change affect the acidification of the world’s oceans or air quality in China and India in the coming decades, and what climate policies could be effective in minimizing such impacts?
